Radical Ties not Ruled out at Ft. Hood

A senior U.S. official in Washington isn't ruling out the possibility that the alleged Fort Hood shooter had ties to radical groups, but isn't saying whether there's evidence to back it up.

Officials now say a 13th person has died in yesterday's rampage in Texas and 30 were wounded. Authorities at first thought one of the dead was the shooter, accounting for a delay in identifying him.

Lt. Gen. Robert Cone, Fort Hood's base commander, told CBS's "The Early Show" that the alleged shooter is rumored to have said "Allahu Akbar," (God is great) during the shooting, but was unable to confirm that information.

As military officials try to piece together what may have pushed Army psychiatrist Maj. Nidal Malik Hasan to turn on his comrades, the wounded suspect is on a ventilator, unconscious and under guard in a hospital.

Law enforcement officials say Hasan came to their attention at least six months ago, because of Internet postings about suicide bombings and other threats. It's not yet certain he authored the posts.
